Metal Industry Pressure & Flow Control Solutions

Proportion-Air helps control pressure and flow in numerous applications across the metal industries. Whether we are helping to atomize air in a die lube spray or provide force control to a steel cleaning process, our products help make your products what you need them to be.

A few more examples:

  • Controlling low pressures for aluminum casting
  • Cooling mold water
  • Controlling gate valve pressure

Many of our best metal industry applications revolve around cooling. Sometimes we are controlling water pressure or water flow to a mold and other times we control the amount of air to a casting process to maintain a specific temperature. In both circumstances, we offer accurate and repeatable results.
